Application filed March 27, 1888. Serial No. 268,693. (No model.)

To all whom it may concern.-

Be it known that I, JoHN llLkRTIN Jaoo, a citizen of the United States,residing at Calf Creek, in the county of Searoy and State of Arkansas,have invented certain new and useful Improvements in Cotton-Gin Gang-SawOleaners; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in cotton gin gangsaw cleaners; andit consits in the construction and novel combination of parts, ashereinafter set forth, illustrated in the accompanying drawings, andpointed out in the appended claim.

The object of my invention is-to provide a cheap and simple means ofcleaning both sides of the gangsaws of eottongins at the same time whenthey become gummed, and to provide, further, a knife that will enter itsentire length between the saws and not twist or bend the teeth.

I have shown my improved cleaner attached to the frame-work of acotton-gin, in which Figure 1 is aplan view'ofmy improved cleanerattached to the frame of a cottoirgin, the saws of the same being shown.Fig. 2 is a transverse section on the line x as of Fig. 1. Fig. 3 is adetailed view of the knives. Fig. 4 is a detail view of one of thebrackets, showing the guideway d.

Referring to the accompanying drawings by letter, A represents the frameof a cotton-gin, and B a shaft turning in suitable bearings and havingsecured upon it a series of saws, G.

D and D designate brackets secured by screws or bolts to the sides ofthe frame-work of the gin. These brackets have guideways or bearings d,in which the sliding block E travels when operated by means hereinafterexplained.

F represents apiece of flat steel, preferably about oneeighth of an inchin thickness, secured to the sliding block ll,and having made integraltherewith the parallel edged knives f, said knives being parallel toeach other and at right angles to the piece F.

G is a shaft journaled in suitable bearings in the brackets D and D, andhaving secured to one of its ends the wheel J for operating the cleaner.

The shaft G has keyed upon it near the ends thereof the pinions H and H,which mesh with the rack-bars I and l, secnred to the sliding block E,as shown.

The operation of the machine is asfollows: \Vhen the saws become gummcdfrom ginning damp cotton, the gin is stopped, and the knives are broughtinto contact with the saws by means of the wheel J,pinions Hand H,andrack-bars I and I. The saws are then turned backward through onerevolutiomand the gummy cotton is then cleaned from both sides of thesaws by the knivesf.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

In a cleaner for the gangsaws of a cottongin, the combination,with thebrackets D and D, provided with the guidcways d, the sliding block E,having secured thereto the parallel knivesf, rack-bars I and l, theshaft G, having the pinions II and H, meshing with the rack-bars, andthe operatingwheel J, sub stantially as specified.
